Dear all, for Ubuntu 16.04 exists no kernel 4.18 and the HWE-kernel (4.15.0-50) crashes also, so it is not possible to boot an Ubuntu 16.04 as PVH at this time. We opened this bug-ticket: <https://bugs.launchpad.net/ubuntu/+source/linux-meta-hwe/+bug/1829378> If you are affected, please subscribe and mark "affects me" also. TU. Best regards, Kelly.
